@lwc/test-runner lacks support for Yarn's PnP mode

Just due to this one library, we need to do work around in one of internal repo which uses Yarn pnp with nodeLinker option as workaround which is heavily used by multiple teams. which affects speed and larger diskspace of dependencies installed for the Repo.

Temporarily we went with work around and don't want to have this work around stay for longer.

Curious, Isn't this become issue for our ISV customers too, if they prefer Yarn PnP mode ? or our ISV customers will never land into this scenario ?
